Global increases in beach sand temperatures are predicted to skew hatchling sexratios of marine turtle populations towards female bias. Currently, shade structures and fresh-water irrigation are management strategies used to cool nest temperatures, but require resources that are limited at remote rookeries. Here, we report on a novel investigation that used seawater irrigation as a sand-cooling method. Various volumes of seawater were applied to sand to deter-mine the optimal application required to lower sand temperatures at nest depth to produce male-biased sex ratios.

Technical report

This  report  on  progress  in  the  Pacific  was  prepared  by  the  United  Nations  Economic  and  Social  Commission  for  Asia  and  the  Pacific  (ESCAP),  in  accordance  with  United  Nations  General  Assembly  Resolution 63/213 (February 2009). A draft version was tabled for discussion at the Pacific High Level  Dialogue held in Port Vila, Vanuatu on 8?9 February 2010. Comments received during the meeting and  the consultation period that followed have been incorporated into this final version.  

As part of the RIF review process, a team of three independent consultants were commissioned to analyse, assess and validate the most appropriate regional institutional arrangements based on a range of options provided by the CEOs of SOPAC, SPC and SPREP. The key rationale underpinning the work was to optimise service delivery, in particular ensuring the SOPAC work programme continued without diminution and was potentially enhanced. This document presents the Final Report of Part Two of the consultancy.
